Unidentified gunmen and suicide bombers raided a Sikh religious complex in the Afghan capital of Kabul on Wednesday, trapping up to 200 people and inflicting casualties before the security forces killed the attackers, the government said.

At least seven people were killed and ten wounded, including four foreigners, when a minivan packed with explosives detonated during Kabul's morning rush hour Wednesday, an interior ministry spokesman said.

A large blast rocked central Kabul Wednesday, officials confirmed, sending a plume of black smoke over the city in the latest explosion to hit the war-torn city and as Afghanistan observes the Islamic holy month of Ramadan.
